Mongolia: Hybrid plant supplies electricity for rural training center
The photovoltaic-wind energy hybrid system supplies the MULS field office with electricity.
About 140 kilometres from the capital Ulaanbaater, in
Nart Töv, lies the training centre of the Mongolian University
of Life Sciences. Until a few years ago, a diesel
generator produced electricity there for lighting, small
electrical appliances and for the pumping of drinking
water. Noise and exhaust pollution was a standard feature.
That changed in 2015 thanks to HEOS Energy. The
company built a photovoltaic-wind energy hybrid system
for the rural branch of the university, which makes
living, learning and working on campus much easier.
A small wind turbine with 15 kilowatts of power generates
37,000 kilowatt hours of electricity per year, while
the photovoltaic system – with 6.44 kilowatts of power
– supplies 11,500 kilowatt hours of solar electricity. The
electricity can be temporarily stored in leadgel batteries.
An emergency generator secures the energy supply
if the power from the other energy generators and the
storage unit is not sufficient.
Encouraged and inspired by the quiet and emission-free
power generation now available, the operators immediately
added the new greenhouse and workshops.
After commissioning, HEOS trained both teachers and
students on how the off-grid hybrid system works and
how to maintain it.
The hybrid plant was built as part of the Renewable
Energy Solutions Programme of the German Energy
Agency (dena) of which is part of the “Energy Export
Initiative” of the Federal Ministry for Economic Affairs
and Energy.
With information and practical experiments on the topics of
photovoltaics and wind energy, HEOS Managing Director, Dr.
Klaus Hoffmann, added variety in the curriculum for the students
of MULS.
